VISOCOLOR® reagent case for soil analysis
Reagent case for soil analysis 

Thorough analysis is a corner stone to support and maintain healthy, productive and biologically active soil. To effectively and efficiently plan all measures that affect the soil (fertilization, liming, etc.) it is crucial to determine the important soil parameters first.

The VISOCOLOR® reagent case for soil analysis is the perfect companion for economical, fast and convenient soil analysis, both in the field or in your laboratory.

Data and ordering information
REF 931 601
Type reagent case for soil analysis

The VISOCOLOR® reagent case for soil analysis contains all reagents, instruments and accessories required for the preparation of soil extracts and the subsequent determination of

  • Ammonium, Nitrite, Nitrate (N)
  • Potassium (K)
  • Phosphate (P)
  • pH

The soil extracts are either prepared with Calcium-Acetate- Lactate (CAL) solution (prior to the determination of P and K) or with CaCl2 solution (prior to the determination of N and pH).

If required by national regulations for soil analysis or because of local geological conditions, the VISOCOLOR® reagent case for soil analysis can also be used together with extraction solutions other than CaCl2 or CAL. Please consult instruction leaflets for possible interferences.

Reagents are sufficient for 110 CaCl2 extractions, 7 CAL extractions and 60 – 100 tests.

Shelf life of reagents: at least 18 months

As refills the following reagents can be used.
